Description

The registered jack that termination variability reduces
Background technology
Because telecommunications is used according to such as IEEE 802.3an 10GBASE-T, ISO/IEC 11801Ed2, higher performance and the controlled more performances of standard-required frequency such as IEC 60603-7-41, ANSI/TIA/EIA-568-B, so modular plug flexible cord (for example terminating to the twisted-pair feeder of modular plug) becomes more crucial.Connector (for example having socket or jack that the printed circuit board (PCB) (PCB) that leads to various terminal block, flexible circuit or lead frame connect) designs and limits (as limiting in TIA and IEC document and other document) according to their performances relevant with the plug performance range that is used for testing them.Can improve the socket performance by the scope/changeability that limits the plug (the modular plug flexible cord that perhaps comprises two plugs) that cooperates with socket.Because most manufacturers sell their connector with its own module plug cord, so can when meeting industrial standard (being TIA or ISO/IEC restriction), the changeability by adjusting and the production of minimizing flexible cord improve performance.
Telecommunications connector usually uses cable with many.Wiring is laid (the one-tenth butted line of the predetermined length that tangles) and is caused line to orientation at the end as other end mirror image around each other.The intrinsic property of twisted-pair feeder causes causing mirror image pattern when cutting one section cable with termination plug.The existing standard plug design has one group of termination pattern, and then this termination pattern requires cable one end or two ends to be crossed as line to being convenient to termination so that they are aimed at rightly.Untiing owing to adding not controlled cross-talk element that this intersection that line is right or manipulation or line are right causes significant change.
In existing plug, indivedual conductors in the front end in contact penetration line cable and contact with back panel wiring.Contact is arranged in the plug body.Yet there is changeability the position of place, contact place and twisted-pair feeder, and this causes electrical transmission to change and dimensional variation.This curling height change causes a plurality of problems, specifically cooperates from the uncertain coupling of plate surf zone and with the inconsistent of socket.Thereby inconsistent curling height may cause in the socket contact that undesirable location arrangements cooperates can't adequate compensation various crosstalk levels.
In addition, in existing plug, the line in the cable unties to take front end in contact to needs.Thereby line is right untie usually the inconsistent and line that causes intersection to cause can't adequate compensation various crosstalk levels.
Therefore, need in the art a kind of telecommunications connector that reduces in order to the termination variability of the performance (for example reducing cross-talk) that improves matching connector.

Embodiment
Fig. 1 is the end view that is connected to the exemplary jack plug 100 of cable 200.Cable 200 comprises four twisted-pair feeders 202.Understand that embodiments of the invention can the cable different from number of twisted pairs use and the invention is not restricted to have the cable of four twisted-pair feeders together.Plug 100 comprises that yardstick sets for and the jack shell 102 that has the modularization socket now and cooperate.Jack shell 102 can be RJ-45 type plug, still can have different configurations.
Jack shell 102 is included in plug contact 106 contact foundation electrical connection between 108 with wiring substrate 104.Wiring contact 108 can be positioned on the contact carrier 110.Substrate 104 can be the printed circuit board (PCB) that wherein has trace 105 (Fig. 6), flexible PCB, multidimensional PCB etc., and these traces are used in plug contact 106 and foundation electrical connection between wiring contact 108.As describing in further detail here, substrate 104 can comprise the compensating element, for the electrical property (for example NEXT, FEXT, return loss, balance) of regulating plug 100.In alternative, thereby some or all contacts that plug contact 106 contacts in 108 with wiring are that the part elimination of lead frame is to the needs of substrate 104.
Plug contact 106 have that being coated with in substrate 104 admit in the through hole 114 by press fit tail portion 112.Trace on the substrate 104 is set up electrical connection between being coated with through hole 114 and wiring contacts 108.Plug contact 106 extends to set up the contact that contacts (not shown) with socket when plug 100 cooperates with the socket (not shown) through the groove 116 (Fig. 2) in the jack shell 102.In alternative, solder plug contact 106 in substrate 104. Plug contact 106 or 108 can have by press fit tail portion, welds afterbody, complies with pin, the fixing afterbody or be used for being coated with through hole 114 or 107 or set up other connection type of electrical connection and mechanical connection at surface-mounted pad of machinery.
Wiring contact 108 comprises through contact carrier 110 extensions and the press fit tail portion of pressing that is coated with through hole 107 (Fig. 6) in contact carrier 110 following bonded substrates 104.Four wiring contact 108 first surfaces from substrate extends, and four wiring contact the 108 second surfaces extensions from substrate 104.The layout permission twisted pair end of wiring contact on substrate 104 received wiring contact 108 and be need not and make their intersections or operate them from its original position at arbitrary end of modular plug flexible cord or other assembly.Here with reference to Fig. 5-8 this feature is described particularly further.
Substrate 104, plug contact 106, contact carrier 110 that Fig. 3 illustrates without twisted-pair feeder contact 108 with wiring.In Fig. 3, wiring contact 108 is insulation-displacement contacts.Insulation-displacement contact 108 longitudinal axis that are oriented to perpendicular to the wiring in the twisted-pair feeder 202.Fig. 4 shows an alternative, and in this embodiment insulation-displacement contact 108 is oriented to become inclination angle (for example 45 degree) with respect to the longitudinal axis of the wiring in the twisted-pair feeder 202.Wiring contact 108 need not to become a line, the thus wider wiring specification of allowed band at same level.In alternative, the insulation-displacement contact is that insulation penetrates contact.
Fig. 5 illustrates four pairs of telecommunications cables 200 with twisted-pair feeder 202.As in this area typically with line to dyeing, wherein pure color wiring tangle with another wiring with same color and white (for example twisted-pair feeder indigo plant of having blue wiring and tangling/in vain wiring).In order to be easy to explanation, figure 5 illustrates for the right color of each line.Embodiments of the invention are not limited to specific wiring color or line pair count.
As shown in Fig. 5, Fig. 7 and Fig. 8, the opposite end of cable 200 mirror image each other with regard to the position of pair of connecting wires.This orientation of pair of connecting wires in cable causes the pair of connecting wires that intersects usually when cable end is received connector.Usually, if line to uncrossed when being terminated at an end of cable 200, then line is to rearranging and intersecting at the cable other end.This is because but conventional connector respectively holds identical pair of connecting wires position respectively to hold the different facts at cable at cable.In this conventional the layout, if pair of connecting wires at one end is uncrossed, then the pair of connecting wires at the cable other end must intersect.Embodiments of the invention are eliminated this problem.
Fig. 6 illustrates the two sides of the printed circuit board (PCB) 104 in the embodiment of the invention.Trace 105 is electrically connected with being coated with between the through hole 114 to set up being coated with through hole 107.Be coated with through hole 107 admit wiring contact 108 by press fit tail portion.Be coated with through hole 114 admit plugs contact 106 by press fit tail portion.Line is represented by identifier OR/W (orange white wiring) and OR (orange wiring), BL/W (blue white wiring) and BL (blue wiring), GR/W (green white wiring) and GR (green wiring) and BR/W (brown white wiring) and BR (brown wiring) the position.For example, quote " blue wiring " and refer to Lan Helan/white wiring.As known in the art, twisted-pair feeder tangles around each other in cable 200.
Fig. 7 illustrates cable pair of connecting wires 202, and each terminates to two substrates 104 at cable 1With 104 2First surface.Described cable to the position in cable 200 301 and 302.Fig. 7 shows two substrates 104 1With 104 2First surface (for example end face) at each end of cable.As shown in the figure, orange pair of connecting wires and blue pair of connecting wires 251 terminate to substrate 104 in the end 1End face on wiring contact 108.Green pair of connecting wires and brown pair of connecting wires terminate to substrate 104 2End face on wiring contact 108.This is with consistent at the natural wiring position of pair of connecting wires shown in 301 and 302 in cable 200.
Fig. 8 illustrates cable pair of connecting wires 202, and each terminates to two substrates 104 at cable 1With 104 2Second.Second finding such as slave plate described cable to the position in cable 200 301 and 302.Fig. 8 shows two substrates 104 1With 104 2Second (for example bottom surface) at each end of cable.As shown in the figure, brown pair of connecting wires and green pair of connecting wires 251 terminate to substrate 104 in the end 1End face on wiring contact 108.Blue pair of connecting wires and orange pair of connecting wires are terminated at substrate 104 2The bottom surface.This with as consistent at the natural wiring position of pair of connecting wires shown in the of 301 and 302 in cable 200.
Above-mentioned example embodiment is used wiring contact position different single substrate 104 for each end of cable.In other words, the wiring termination configuration on each end of cable is different in order to prevent the intersection of pair of connecting wires.Wiring contact 108 is positioned substrate 104 1End face on to be used for orange and blue line to (Fig. 7).Wiring contact 108 is positioned substrate 104 1The bottom surface on be used for brown and green line to (Fig. 8).At substrate 104 2The configuration that upper use is opposite.
The embodiment of Fig. 7 and Fig. 8 uses same substrate 104 at each end of cable 200.In alternative, use two different substrates, substrate is used for each end of cable, and wherein trace differently is configured to the wiring in the cable is mapped to the plug contact and need not pair of connecting wires is intersected or to reorientate at the arbitrary end of cable.In more embodiment, use have be embedded in 2 layers or more multi-layered in the monobasal of many groups trace.Second group of trace that substrate comprises for the first group of trace that uses with the First Line cable-end and is used for using with another cable end.
Be positioned on the opposite face of substrate by contacting in the wiring that will be used to into butted line on the opposite end of cable, the pair of connecting wires in the cable 200 need not to intersect at an end of cable.For example, blue pair of connecting wires terminates to substrate 104 1End face and terminate to substrate 104 2The bottom surface.This and blue pair of connecting wires are in the position consistency of the each end of cable 200.Therefore, pair of connecting wires 202 need not to intersect and pair of connecting wires is untied also minimum.The electrical property changeability that this causes more predictable wiring termination and reduces the modular plug flexible cord is because the wiring termination is more measurable.When the electrical property of modular plug flexible cord has when still less changing, be easier at substrate 104 or the other places in passage (for example socket, cable) compensation electrical property (for example NEXT, FEXT).
In addition, this design allows the larger conductor termination of diameter to plug.Existing plug has fixed width, and these plugs are limited to 24 AWG conductors of termination usually.Since shown in plug embodiment cable is centered at around the substrate and two pair of connecting wires at end face and two pair of connecting wires in the bottom surface, so plug can 23 and 22 AWG conductors 202 of termination.Therefore, example embodiment can termination have scope at the cable of the conductor 202 of 27 AWG to 22 AWG.
Can regulate with the feature on the substrate 104 such as circuit trace the electrical property of plug.Can carry out the adjusting of plug to solve electrical performance characteristics such as near-end crosstalk (NEXT), return loss, far-end crosstalk (FEXT) and balance.Because pair of connecting wires need not to untie or intersects with the termination pair of connecting wires, so can (change less) more accurately and (target performance level in concrete allowed band) adjusting plug 100 more accurately.Figure 12 illustrates the scatter chart of plug NEXT value, and these curve charts illustrate can accept plug performance range 300 and such as the performance of the plug 100 of curve chart 302.Figure shows the district's band that narrows down for plug 100 attainable plug NEXT values, this equates more measurable and controlled parts.Figure 12 is an example of concrete condition, and this example has illustrated that 36-45 line is to the permission plug NEXT scope of the classification 6A of combination.Same concept can be extended for other line of other classification to combination and other transformation parameter.Can accept plug performance range 300 can be limited by standards such as classification 5e, 6,6A.Can come measurement performance for various electrical quantitys such as NEXT, FEXT, return loss, balance.The performance that strengthens causes the higher overall channel performance of unit cost.This also allows the socket complexity that cooperates with plug lower, because plug focuses on a certain performance level.Thereby socket only need have for certain plug performance rather than the electrical property of plug performance on a large scale.Suppose to be easy to termination and without pair of connecting wires operation, then plug can be by setter termination and target capabilities still is provided on the spot.
In addition, allow to adjust the plug performance characteristics to strengthen the performance of whole passage in order to the ability of regulating the electrical property of each plug on the modular plug flexible cord.For example, the first plug on can adjustment module plug cord one end with in the low side work of limited range and the second plug on the adjustment module plug software other end with the high-end work at limited range.In example embodiment, this limited range relates to classification 5e, 6,6A and the more high-performance as being limited by industrial standard ANSI/TIA/EIA-568-B (/ 568) commercial buildings telecommunications line standard and ISO/IEC 11801 (/ 11801).In No. the 20040116081st, the U.S. Patent Application Publication that by reference full content is incorporated into this, the adjusting plug has further been described particularly to realize a certain transmission performance.
The assembling of plug is described with reference to Fig. 1.Initial step relates to being coated with through hole 114 plug contact 106 is inserted in the substrate 104.Plug contact 106 can have by press fit tail portion, welds afterbody, complies with pin, the fixing afterbody or be used for being coated with through hole 114 and setting up other connection type of electrical connections and mechanical connection of machinery.Wiring contact 108 has the afterbody that is coated with through hole 107 of putting into substrate 104 through contact carrier 110.Wiring contact 108 preferably has by press fit tail portion.Wiring contact 108 can contact by insulation-displacement (IDC) and set up and being electrically connected of wiring 202.Alternatively, wiring contact 108 can be that insulation penetrates contact (IPC) or solder terminal.These operations cause as shown in Figure 3 sub-component.
Then use known technology that terminals are received wiring contact 108.The sub-component of Fig. 3 can partly be inserted in the jack shell 102 before the wiring termination.Say that as above the pair of connecting wires 202 on each end of cable 200 need not to intersect or rearrange, because in wiring contact 108 positions of reflection pair of connecting wires in cable 200 of the each end of cable 200.In case pair of connecting wires 202 terminates to wiring contact 108, substrate 104 is slided in the jack shell 102, thereby plug contact 106 is aimed at groove 116.Be latched in fixing base in the shell 102 by frictional fit and/or by one or more that substrate 104 is fixed.
In the alternative of here discussing, wiring contact 108 exposes when substrate 104 fully is inserted in the shell 102.Pair of connecting wires 202 terminates to wiring contact 108 as mentioned above.Non-conduction strain alleviates member and then slides on cable 200 and be attached to shell 102 to cover wiring contact 108.
Fig. 9 illustrates the exemplary substrates 404 in the alternative.Substrate 404 uses IPC 406 in order to set up and being electrically connected of wiring 202.Plug contact 408 is the wiring contacts that comprise from the cantilever of post extension.Styletable is positioned to be coated with in the through hole 114 (for example weld, by interference fit).Arm extend back and comprise can with the pad 420 joints that are electrically connected 410.Be coated with through hole 114 can be coated with through hole 107 and be electrically connected.Pad 420 can with admit wiring contact 406 the through hole 107 that is coated with electrical connection is arranged.Pad 420 can be electrically connected to compensating element, on the substrate 404 (reactance, electricity are led, electric capacity, phase control), thereby when joint 410 contact pad 420, contacts 408 and be connected to compensating element.Can realize phase adjusted with the technology of in No. the 20040147165th, the U.S. published patent application that by reference full content is incorporated into this, describing.This layout allows by setting up between joint 410 and the pad 420 or forbidding being electrically connected fetching and one or more is contacted 408 selectively compensate.
As above say, replace the substrate such as PCB, plug can utilize wherein wiring contact 108 to contact 106 with plug and be formed at the leadframe design that shares on the metal lead wire.In this optional mode, the position class of wiring contact is similar to position shown in Fig. 7 and Fig. 8, thereby the wiring that pair of connecting wires need not to be intersected to terminate at each end of cable contacts.
Embodiments of the invention allow pair of connecting wires to be terminated on the equipment and to need not to make line to intersecting or splitting line pair from arbitrary end, as in the situation of industrial standard connection plan TIA-568A/TIA-568B.Plug contact 106 can have non-standard profile to increase performance and to eliminate the changeability of height and position.More consistent electrical property is facilitated in variable minimizing.This also causes cost reduction, because need operator's input still less in the manufacturing of plug.
With reference to plug above-described embodiment has been described.The wiring termination also can be used with other connector such as modularization socket.As mentioned above, the modularization socket comprises such as the such substrate of substrate shown in Fig. 5-8 or comprises lead frame, thus position reflection pair of connecting wires position on each end of cable of wiring contact.
